Abstract

The DC60 (25/12/40) device comprises a signal source (FLY) synchronized with the horizontal component of the image signal (overall signal); a section (FBPB detector) that responds to the synchronized signal for signal generation (FBP') representing the horizontal flicker; a section (image signal processing/integration) for generating the image-blocking signal (H-BLK) for electron beam inhibition during the horizontal flicker; a section (phase-to-DC converter) that responds to the signal representing the horizontal flicker and the image-blocking signal for generating the reference signals (VR1, VR2) representing the time of the image-blocking signal; a section (H-BLK detector) connected to the image-blocking signal generator and the reference signal generation section that creates a feedback loop; and a section (phase shifter) for generating an image-blocking signal with the phase corrected (H-REF*) according to the time of the image-blocking signal to control the image-blocking signal generator in a feedback loop where the image-blocking signal occurs during the flicker. The device comprises a signal source (FLY) aligned with the horizontal component of the image signal (overall signal); a section (FBP sensor) that responds to the aligned signal for generating the (FBP) signal representing the horizontal flicker; a section (image signal processor/integrator) for generating the image-blocking signal (H-BLK) for inhibiting electron beams during the horizontal flicker; a section (phase-to-DC converter) that responds to the horizontal flicker signal and the image-blocking signal for generating the reference signals (VR1, VR2) representing the time of the image-blocking signal; a section (H-BLK detector) connected to the image-blocking signal generator and the reference signal generator that creates a feedback loop; and a section (phase shifter) for generating the image-blocking signal with the phase corrected (H-REF) according to the time of the image-blocking signal to control the image-blocking signal generator in a feedback loop where the image-blocking signal occurs during the flicker.

1. The device consists of a signal source (FLY circuit) that is synchronized with the horizontal component of the image signal (overall signal); a section (FBP sensor) that responds to the synchronized signal for generating the FBP signal representing the horizontal flicker; a section (FLY processor/image signal merging) for generating the image-blocking signal (H-BLK) for cross-electron beam during the horizontal flicker; a section (phase-to-DC converter) that responds to the signal representing the horizontal flicker and the image-blocking signal for generating the reference signals (VR1, VR2) representing the time of the image-blocking signal; a section (H-BLK detector) connected to the image-blocking signal generator and a reference signal generation section that creates a feed loop; and a section (phase shifter) for generating the phase-corrected image-blocking signal (H-REF) according to the time of the image-blocking signal to control the image-blocking signal generator in a feedback loop where the image-blocking signal is present. Occurs during the horizontal recoil phase (Clause 1, Page 1, Figures 3).
